To all whom it may concern:

Be it known that l, ERNns'r J. Gnoonn'rr, a citizen of the UnitedStates, residing at Los Angeles, in the county of lLos Angeles and State of California, have invented a new and usefulReceptacle-Makin Machine, of which the following is a speciiication.

An important object of this invention is the provision of a machine for producing a terial in layers as to produce maximum smoothness of the inside and outside surfaces of the receptacles. i

Another object is to so wind strip material as to make the winding operation con tinuous.

Another object is to produce a machine capable of manufacturing each receptacle in a minimum amount of time.

Otherobjects and advantages may appear from the subjoined detail description.

of said layers, and the helical turns of alternate layers progress a'slant toward one end of the receptacle and the helical turns of ad]acent layers progress aslant toward the opposite end of the receptacle and adjacent layers overlie one another.

Spools 1, 5, 6 to hold cartridges or rolls of strip material such as paper or other fibrous material are mounted on suitable spindles 7 carried by a standard 8 of a bracket 9. The spools 4C, 5, Gare in staggored relation with one another and the strips 10, 11 from the lower spools 4, 5 are threadedove'r a guide or roller 12 mounted on the standard and the strip 13 from the upper spool 6 is threaded under saidroller. All of the strips 10, 11, 13 are threaded around a guide roller 14: mounted on the bracket 9 and over a roller 15 which is rotatably mounted on an adjusting arm 16 pivoted to a feeder head 17 swivele-d on the Patented May 211, ilwld.

upper flanged end of an oscillating feeder arm 18 which carries the bracket 9 said arm 16 being pivoted to a connecting rod 19 that in turn is pivoted to an operating lever 20. The operating lever 20 is pivoted to said feeder head, so that movement of the lever p 20 will raise and lower the roller 15 in binder is spread on the under surfaces of the strips 10, 11, 13 by the distributing roller 21, as the strips pass over said roller.

The strips 10, 11, 13 are threaded from the distributing roller 21 over a guide roller 23 rotatably mounted on the feeder head 17. The rollers '12, 14, 15, 23 may be provided with flanges Qtto prevent the edges of adjacentstripsoverlapping one another. The feeder arm 18 is pivoted at its lower endat 25 to a suitable frame 26 and is pivoted intermediate its ends at 27 to one end of an actuating rod 28 which is provided at its opposite. end with a pivot 29 engaging a slot 30 in the lower end of a lever 31.

The lever 31 is fulcrumed intermediately at 32 to the frame 26 and is provided at its upper end with a slot 33, see Fig. 6, engaged by a stud 3 1 which projects from a collar 35 reciprocably mounted on a camshaft 36 grooves 39 being approximately one-half of a straight turn.

The grooves 37, 38, 39 accommodate a crescent shaped follower 40, see Fig. 6, having a stud 41 projecting into a seat 42 located in the collar 35, said seat extending up through a boss 43 that is externallythreaded to receive a cap 44 into which is screw threaded a lubricating cup 45.

The camshaft 36 rotates in bearings 46,

i 47 of the frame 26 and is provided on its outer end with a sprocket wheel 48 engaging a'sprocket chain 49 which is driven by .a sprocket wheel 50 mounted on the outer end of a shaft 51 journaled at 5.2, 53' on the frame, said shaft being provided with fast and loose pulleys 54, 55 to receive a driving belt," not shown, which thus drives the shaft 51 when said belt engages the fast pulley 54 and which'can be shifted by the usual means, not'shown', from said fast pulley to the loose pulley 55 when it is not desired to operate the machine.

The shaft 51 turns a collapsible core of suitable construction and in the instance shown, said core comprises heads 56, 57 and an intermediate barrel shaped core-body formed of longitudinally curved segments 58, 59 which are pivoted at 60, 61 to arms 62, 63 respectively that are pivoted at 64 to hubs 65 fastened by keys 66 or the liketo the shaft 51, said arms 63v being. sectional and provided with knuckle joints 67. The arms 63 areprovided at their knuckle joints with complementary beveled ends 68 so that said arms can fold only toward the head 57..

The shaft 51 is provided-with a conical centering end 69, and the head .56 is provided with a hub 70 fastened by a key 71 or the like to the shaft 51, and the head 57 is provided with a centering pin 72 fastened to said head by a key 73 or the like, said centering pin having a conical centering end 74 designed to be inalinement with the centering e'nd69 of the shaft when the head 57 is in place. I Thecentering pin 72 is provided with a conical centering socket 75 to receive the conical end of 'a pivot' 76 which is mounted in one end of a swinging arm'77, that is pivoted at the other end at 78 to a bracket 79 of the frame 26, said swinging arm 77 being yieldingly held toward the head 57 to hold said head in place by a coil spring 80 fastened at its opposite ends to the swinging arm 77 and frame 26.

The head 56 is provided in its outer face with a slot 81 to receive one end of a spring clip 82 having its otherend bent over the periphery of said head to hold the ends of the strips 10, 11', 13 as in vFig. 3.- The upper endof the feed arm 18 is provided with a socket 83 to receive the pivot. 84 of the head 17 and is provided with stops 85, 86 projecting up into the path of the head, said stops being spaced apart so as to allow the head to swing at different angles' pitch or angle of progression of the helical turns a, b of thestrips.

I have provided means for alternatively turning the head 17 first at an angle coinciding with the angle of progression of the helical turns a and then at an angle coinciding with the angle of progression of the helical turns 6, and said means are constructed as follows:

The head 17 is provided with downwardly projecting lugs '87, 88-. forming stops designed to engage stops 89, 90 respectively in the form of collars fixed by set screws 91 to a rod 92 which passes through the lugs and is fastened by nuts 93 to a bracket 94 of the frame 26.

The collars 89, 90 are fastened at such positions on the rod 92-as to enga e the lugs 87, 88 respectively. When the ollower 40 is near the ends of the respective cam grooves 37, 38 so that when the follower passes into the rooves 39 the head will have been turned su ciently to engage the stops 85, 86' respectively.

The core segments 58, 59 are provided at their ends adjacent the head 57 with points 95 projectin toward the inner face of the head 57 for t e reason hereinafter set forth.

In practice the tank 22 will be provided by the attendant with a suitable substance such as silicate of soda or the like, and the spindles 7 will be supplied with spools of strip material such as paper or other suitable fibrous substance and the strips 10, 11, 13 will be threaded to engage the guide rollers 12, 14, 15 and 23. The lever 20 will be operated to raise the roller 15, thus to hold the strips 10, 11, 13 free from the distributin roller 21. A permanent head 96 of woo vor other suitable material having centering sockets 97 will then be placed at the forward end of the core between the corebody and the head 57 and forced against the points 95 to embed said points in the permanent head, see Fig. 4, said points holding the permanent head against rotation relative to the core.

Assuming at the start that the feed arm 18 is in such position that the roller 23 is directly over the head 56, the free ends of the strips 10. 11. 13 will be fastened under the spring clip 82 and the machine will then be started into operation by turning the drivinseam lng pulley 54 by a power driven belt, not shown, so as to turn the core in the direction of the largefeathered arrow 98, Fig. 1, to wind the strips with abutting edges in helical turns a progressing toWard' the head 57 to form an inner layer 0. When the cam shaft-36 has rotatedsufliciently to swin the feed arm 18 far enough so that the feediead 17 is adjacent the head 57 the layer 0 iscon1- pletcd, and the collar 90 will engage the lug 88 and turn the head 5'? against the stop 86.

Then the lever 20 will be operated to lower the roller 15 to allow the strips 10, 11,13 to contact with the distributing roller 21 and said cam shaft 36 reverses the movement of the feed arm 18 so as to wind the strips in a reverse direction in helical turns 6 overlapping the turns 0 in the first layer and diagonally crossing the turns of the first layer,

thus forming a second. coated layer (5 bound by the silicate of soda to the. first layer. At the end of this movement the collar 89 engages the lug 8,7 and turns the head 1? preparatory to winding a third layer.

Thus the feed arm 18 is caused to swing to and fro to wind the strip materialto and fro around the core as the core revolves'and the winding operation is continueduntil any desired number of layers have been wrapped on the core to form a tubular body, there being two or more layers according to the use to which the receptacle is to be put.

When the desired number of layers have been formed,the operator will sever, the un-" Wound portions of the strips .10, 1 1, 13 from the wound portions thereof. and trim off sufficient of the wound strips at the head 57 to free saidhead from being, held by the strips and he will then swing the arm 77 away from the head 57 and remove said head. Then he will grasp the arms 63 and bend the same at the knuckle joints 67 to cause thesegments 59 to be drawn radially inward toward the shaft 51. The operator will then grasp the tubular body and pull the same forwardtogether with'the permanent head 96 away rom the head 56, thus causing the arms 62 to swing forward and the se side 0 the segments 59 so as to free the tubular body from the core.

The strips 10, 11, 13 will then be trimmed off by hand or otherwise and the receptacle may be finished off in any suitable manner, as, for instance, disclosed in my co-pendin application for receptacle, filed March 1", 1915, Serial No. 14,913.

The process or method outlined above is not claimed herein but is the subject of my co-pending application for method of making receptacles, filed March 30, 1915, Serial No, 18,002.

Thepivot 25 is so located relative to the roller 23 that when the ar1n18 swin 's said roller will move in a curve corresponding to ents 58 to collapse inward, alongthat 1 do not limit the scope of the invention to the exact construction shown in'the drawings for effecting such result.

The swinging of the roller 23 in a curved path and also so that the axis of said roller is normal to the angle of progression of the helical turns produces maximum smoothness and tightness of the turns.
